We kindly got a whole bunch of the Raspberry Leaf given to us by http://www.monkmakes.com for my recent trip to Kenya and Rwanda - many thanks! One thing I like about the Raspberry Leaf is that the UART RXD is printed in green: Very subtle reminder as to which cable to plug in! The other thing that's nice about this one is that it has both the GPIO labels (for all GPIO) as well as specific functions (such as UART) printed on. The others are one or the other.
